NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 728,665, dated May 19, 1903.

Application filed October 16, 1902.

T0 at whom it may concern;

Be it known that I, CHARLES C. BORDER, a citizen of the United States, residing at Richmond, in the county of Wayne and State of Indiana, have invented certain new and useful Improvementsin Nut-Locks, of which the following is a specification.

My invention relates to improvements in nut-locks; and the object of my invention is the provision ofva nut-lock which will look a. nut upon the bolt and prevent the nut fromworking loose or becoming detached and which will be inexpensive and practical.

With this object in view my invention consists of a nut-lock embodying novel features of construction and combination. of parts, substantially as shown and described herein.

Figure 1 represents a side elevation of my nut-lock, and Figs. 2 and 3 represent detailed views of said nut-lock. Figs. 4, 5, and 6 represent similar views of a modified form of my nut-lock. Figs. 7, 8, and 9 represent similar views of another modified form, and Figs. 10,

11, and 12 represent similar views of anothermodified constructionof my nut-lock.

In the drawings, A designates the bolt, having the vertical groove or channel B and the threaded end 0, which receives the nut D, formed with a recess or seat F, 'havingthe vertical wall of said recess formed withteeth G, and in said recess is carried the split ring H, of spring material, having one end formed with an inward-extending lip J, which ongages the groove of the bolt,vand the other end of the spring-ring is formed with an in-. clining finger K, which engages the teeth of the nut, the said spring thus acting to lock the nut at any point upon the bolt. v

In the form of my nut-lock shown in Figs. 7, 8, and 9 I provide the washer with the seat Serial No. 127,571. (No model.) 7

or recess L and form teeth M'onthe face of the nut, and in said recess 1- place the spring-ring N, which has the lip O for engaging the groove of the bolt and has the off-' set finger P to engage said teeth on the nut.

In the form of my nut-lock shown in Figs. 10, 11, and 12 I dispense with the recess L and form the inner face of the nut with teeth Q, which are engaged by the finger R on the spring-ring S, having the lip T, which engages the groove of the bolt.

In all the forms of my nut-lock the action of locking the nut upon the bolt is precisely the same, and it will be understood that the nut can be turned home upon the bolt, and the spring-washer will lock the nut at any place upon the bolt and will absolutely secure the nut against working loose or becoming detached. It will also be noticed that my nut-lock is of extremely simple construction and can be manufactured at a price which will make it useful and practical.

I claim The nut-lock herein described, consisting of the bolt having a vertical channel, the nut on the bolt having the annular recess with its vertical Wall formed with teeth, a split ring surrounding the bolt and arranged in the recess and having one end formed with an inward-extending .lip engaging the channel of the bolt and the other end adjacent to said end and formed with a tapered offset spring-finger engagingthe teeth on the nut.

In testimony whereof I affix my signatureinpresence of two witnesses.

CHARLES o. BORDER.
